Blue Sea Systems 187-Series 90 Amp Circuit Breaker - Surface Mount with Waterproof Design

Blue Sea 187-Series 90 Amp Circuit Breaker Surface Mount

The Blue Sea Systems 187-Series 90 Amp Circuit Breaker (Part Number: 7143-BSS) is designed for reliable circuit protection and switching in marine and vehicular applications. This surface mount circuit breaker combines a robust thermally responsive bi-metal blade with a clear, single lever operation for easy status monitoring and control. Its trip-free design ensures that it cannot be held in the "ON" position during fault conditions, providing added safety and protection for your electrical system. The waterproof construction and recessed mounting holes deliver a clean appearance while safeguarding against environmental elements, making it suitable for marine environments where moisture resistance is critical.
Large terminal studs with high torque capacity allow for secure connections with heavy-gauge wiring, ensuring consistent electrical contact and reducing the risk of connection failure. The large lever, which can be oriented vertically or horizontally, offers a visual indication of the trip status, simplifying troubleshooting and system monitoring. The device is ignition protected, meeting SAE J1171 standards, making it safe for installation aboard gasoline-powered boats. With a maximum voltage of 48V DC and an interrupt capacity of 5000A at 12V, this circuit breaker can handle high inrush currents, although it is not recommended for use as a switch in such scenarios.
Constructed from durable materials, the Blue Sea 187-Series circuit breaker is a dependable component for marine or automotive electrical systems. Its compact design and high-quality terminals provide a secure, high-torque connection, ensuring long-term performance and safety. The breaker is also compliant with Prop 65 warnings, noting potential health risks, and is designed to meet rigorous safety standards for demanding environments. Overall, this circuit breaker offers a combination of safety, durability, and ease of use, making it a top choice for circuit protection in challenging conditions.
